Sample GSM8027709 Query DataSets for GSM8027709
Status Public on Jun 19, 2024
Title Old Biological Rep 2, Passage 2, input
Sample type SRA
 
Source name dermal fibroblasts
Organism Homo sapiens
Characteristics cell type: dermal fibroblasts
chip antibody: none
age: 97
passage number: 2
Growth protocol All fibroblasts were thawed in passage 2 (P2) and maintained in Human Dermal Fibroblast Media (#116-500, Cell Applications). Media was refreshed every other day and fibroblasts were passaged using Tryple Select (12563011,Gibco) when culture dishes were >80% confluent.
Extracted molecule genomic DNA
Extraction protocol ChIP experiments were performed on chromatin extracts according to the manufacturer's protocol (ChIP-IT High sensitivity, Active Motif, Cat.n. 53040) and chromatin sheared using the Bioruptor system (Bioruptor Plus, diagenode, Cat.n. B01020001) between 30-45 cycles (each cycle 30 sec ON/ 30 sec OFF high voltage).
ChIP-Seq library preparation and sequencing reactions were conducted at Novogene Corporation Inc (Sacramento, CA, USA).
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NovaSeq 6000
 
Description Input/Control
OLD_P2_Merged_fe.bw
O2P2_peaks.narrowPeak
Data processing Trimming (Trimgalore)
mapping (Bowtie2)
Callpeak ran on merged replicates for each tissue/passage (MACS2) using Inp (control) and IP to find fold enrichment. CD4 samples have no Inp file, online ENCODE file ENCFF918OQM.bam was used instead.
bigwig file called (bedGraphToBigWig)
Assembly: hg38
Supplementary files format and content: bigwig file containing fold enrichment signal track for either neonatal P2 merged, old P2 merged or CD4 samples (all donors) merged
